説明

This paper describes an image processing to translate a line image, reconstracted by pasting flame images into Braille codes. We define a series of windows located on the peak points of line image histogram. And then, each window histogram is expanded by using a set of the orthogonal functions. As results of discrimination tests, we find that the coefficients from 1_st to 4_th order are effective in specifing the number and position of raised points, that is, Braille code.
